It allows for interaction through avatars in a computer-based simulated environment, which can be used for purposes like therapy and art installations. Therefore, the correct answer is option B. Virtual reality.
The technology that blocks out the real world and submerses the user in a realistic depiction of reality is known as Virtual Reality (VR). VR is a computer-simulated environment that can range from simple 2D interfaces to highly immersive 3D worlds where users can interact through avatars. It encompasses not only the visual sense but is increasingly addressing other senses to create a full sensory experience.
Virtual reality can be used in various fields, such as virtual reality exposure therapy where it helps people overcome fears by simulating the feared object or situation. Additionally, VR has made significant contributions to the arts, such as in installation art and has also become a platform for exploring new forms of simulated reality where the boundaries between the real and the virtual are increasingly blurred.
